Effects of Salicylic Acid Priming Application in Some Switchgrass (Panicum virgatum L.) Cultivars

Abstract

This study aimed to determine the effects of salicylic acid (SA) seed priming applications on the germination parameters of switchgrass (Panicum virgatum L.). The research was carried out in Siirt University, Faculty of Agriculture, Field Crops Laboratory, under controlled conditions at 25±1 °C. The subject of the study consists of the SA priming doses which is (0, 0.10, 0.25, 0.50, 0.75, 1.00 and 1.25 mM) applied to 3 different cultivars of switchgrass (P. virgatum L.) (Kanlow, Shawnee and Trailblazer). The experiment was carried out in Petri dishes according to the randomized complete design with four replications. In the study, germination parameters such as germination percentage, mean germination time, germination index and coefficient of uniformity of germination, and seedling growth parameters such as seedling fresh and dry weight, seedling vigor index were examined. It was detected that all parameters except for seedling fresh weight were statiscally differences among the cultivars (p
